similar to: llvmcpy: yet another Python binding for LLVM

There is llvmlite http://llvmlite.readthedocs.io/en/latest/ , but it doesn't seem to support reading individual instructions, based on these docs. I was thinking to make a simple code analysis tool to, for example, find all system calls that have unchecked return codes, but I can't find a binding for any scripting language. And I am averse to writing this in C++. Thanks, Yuri

Hello, We are happy to release version 0.10.0 of llvmlite. llvmlite is a light-weight Python binding for LLVM (compatible with Python 2.7 as well as Python 3.4 and later). It stems from the needs of the Numba community and is geared towards creating JIT compilers. llvmlite is available both as source code and as binaries for a number of platforms. Source code is available on PyPI and Github:

​Hello all, I have written a code in llvmlite. Using command numba --dump-llvm example.py > example.ll I can have .ll file. However, using lli example.ll, I am stopped with error: 'main' function not found in module. Is there anyway at which it can be executed using lli?

Hi, sometimes when dealing with LLVM IR getting to a desired point of the code is a bit cumbersome, in particular if you're instrumenting existing code. A lot of nested loops and if checks. Maybe all of this could be avoided by employing a query language. Since an LLVM module can be seen as a sort of tree with attributes, I think that reusing an existing query language for XML would be

For the record, in llvmlite and Numba we don't require C API stability for two reasons: 1) the C API is not enough for us and we rely on bits of the C++ API 2) we also rely on other details

As much as I'm not a fan of most XML things, this application of XPath is *inspired*. This would be a great testing/query tool for tests. It would also be a great way to prototype passes. Looking forward to seeing something like this in llvm/tools/ ! Cheers > On 1 Nov 2017, at 04:00, Sean Silva via llvm-dev <llvm-dev at lists.llvm.org> wrote: > > This is so cool! I once

​Hi all, I am using llvmlite for pyvex and I want the output of my code (which is written based on llvmlite) to be like pyvex. In pyvex, (https://github.com/angr/pyvex). Considering pyvex, I tried to implement the following statements in pyvex to llvmlite: for stmt in irsb.statements: if isinstance(stmt, pyvex.IRStmt.Store): print "ST%s(%s) = %s" % (self.endness[-2:].lower(),

Hi there, Sorry, I don't have the thread history to reply to since I normally read llvmdev through the archives, but wanted to give my .02 of feedback anyway. As far as I understand, this change is wanted because the LLVM infrastructure derives no value from knowing the types, and there's a cost in terms of code spent to support all of it. I've been creating a frontend that mostly

Hello everyone I am Germano, from Italy. Sorry to intruding, but I don't know who to ask anymore. I developed a small programming language, entirely written in Python. I state that I work under Windows, I'm using anaconda and Python 3.6. I wrote the lexical generator and the parser generator. Now I have to write a code generator and thought about using LLVM. It seems that the Uncio way to

Well, nothing has changed in the issues that I brought up earlier, except that I can confirm core dumps in non-threaded lisps as well (CLISP), using svn version 37840 (this morning, Seattle time) for R-2-3-patches. I've not tried Thomas' suggested fixes, as I'm hesistant to go down the road of fixing R in such a way that would require constant patching. (so for those counting,

If you pass an invalid fd to the libc, it replies with a EBADF, it doesn't crash hard. Most mature libraries have guards

Hi, I've recently run into a problem of missing !dbg metadata after the code has been optimized (even opt -O1). The original code was generated using llvmlite python package and I've verified that all instructions have their !dbg metadata present. After optimizing the module (even opt -O1) I see that some instructions (~25%) don't have any dbg metadata. These are mostly getelementptr

Ok, so yesterday it worked. Can you run this for me and mail me the output, i have a quick check. https://raw.githubusercontent.com/thctlo/samba4/master/samba-collect-debug-info.sh And https://raw.githubusercontent.com/thctlo/samba4/master/samba-check-db-repl.sh Last, have you check for corrupted filesystem and/or file/folders?

Hi all, First, I just want to say thank you for the excellent LLVM project. I have been playing with LLVM for the first part of this year and have been quite impressed with what I've seen and what is possible. I've been coding for a long time, but haven't had this much fun since I first learned Python. The work you have done has opened the door for a tremendous amount of
